Application filedseptember 28,1908. Serial No. 455,049.

To all whom 'it may concern:

Be i known thatwe, WILLIAM E. KILLEN and ELwooD C. PHILLIPS, citizens of the United States, residing at Chicago, in the. county of Cook and'State of Illinois, have invented certain new and usefuljlmprovements in Vehicle-Wheels; and we do hereby declare the following to be a full, clear, and exact description of the inventionf-su'ch as Will en.-

pertains to make and use the same.

Our inv'ention. relates to the construction of vehicle wheels and particularly to the rim 0rd. simple, secure and efiicient means for removab y securing the tire to the body of the wheel. i

The rincipal feature of our invention,

is a plan view 0 the devices illustrated in Fig. 1, the tire being removed; Fig. 3 is .a

plane-of. the line 33, Fig. 1; Fig. 4 is a de tail erspective view'ofthe eccentric member y which. the removable tire, carrying rim is actuated; Fig. 5is a fragmentary view showing in inverted plan one means for lockis adetail pers ective view of one of. the members. by w oh the eccentric member communicates movement to. the removable rim; Fig. 7 is a view-v similar to Fig. 1, but

illustrating another form of our invention; 7

and Fig. 8 is a section taken in the plane of the line 88, ,Fig. 7, the interlocking devices carried by the felly being shown in elevation.

ferential face a means-of the said bolts-C.

Like symbols refer to like parts Wherever they occur.

We will now proceed to describe our invention more fully, sothat others skilled in'the art to which it appertains may apply the same. I

In the drawings, A re resents the spokes and B the felly of a whee constructed in ac- These parts of the wheel maybe of any. well-known or suitable form, except that the felly B is appropriately cut away or otherwise fashioned to receive and permit the operation of the eccentric'member D and associated devices by which the locking and unlocking movements of the removable rim are controlled.

The removable rim is secured to the'wheel body by interfitting devices formed upon or.

carried by the rim and felly. 'Theinterlocking means carried by the felly B for cooperating with the rim E may consist of a metal band C which is secured to the periphery of the felly and which'is provided with 'a circumferential bead or projection 1 that is adapted to engage a corresponding groove or depression 1 formed upon the inner circumference of the said removable rim E; or the said means may be formed as an interrupted circumferential bead consisting, for example, of tee-bolts, such as C six or eight of which placed at-equal intervals around the circumference of the wheel will be found amply suflicient. v

When the construction shown in Figs. 7 and 8 of'the drawingsis adopted, the removable rim E having the continuous circumferential, recess or channel 1 maybe employed if desired, but it is preferred to use a removable rim E' having on its inner circumplurality of independent sockets or recesses e which are adapted toreceive and fit the heads of the bolts (1. By the use of a removable rim having inde endent re- 7 cesses for engaging the interloc 'ng means carried bythe felly, any possible tendency for the said rim to creep circumferentially 'ispositively overcome without throwing any strain upon the eccentric D.

If the f "11y B employedin connection with the bolts C is-of wood, itis desirable to reinforce the same by means of a flat metal band C which conforms to the periphery of the folly and is conveniently secured thereto by Both of the removable rims E ,and E, which except as otherwise described may be of-the common clencher typezwith integral tire engaging flanges, are divided transversely, as at 2, thus forming split rings the diameters of which may be increased and decreasedfor a pur ose'which will hereinafter appear. Pivota y mounted u on the inner clrcumferential face of eachof t e removable 15 rims at pointsadjacent to and on opposite sides of its division line 2 are yokes F which are-formed with circular openings 1 to receive and co-act with the corresponding cams or eccentrics 1 1? borne by member D. The eccentric. member D, which passes through an aperture in the felly B, is provided at its inner end with a wrench seat 2 and at its outer end with an enlarged head 3 which is s aced from the gpper cam l a sufficient distance to ermitj'the ends of the removable rims to lie etweefrsaid lead and cam, the abutting ends of said rims and E at 2 being formed with semi-circular recesses for this urpose. By this construction the ends of t e removable rim are maintain edi'in alinement with each other and relatlve. movement radially, which would be ,likely to injure the tire, is prevented. The eccentric member D is preferably formed passageor bore which receives the valve stem. connected to the inner tube and prevents itfrom ere ping ,or being cut. The valve G, which i in .threaded engagement with the eccentric member D, may be of any usual or preferred construction.

I When the pneumatic tire H isinflated the friction of the several parts of the device is generally sufficient to maintain the eccentric member D in its rim locking position; but in order to certainly prevent any accidental turm'ngofthe eccentric member D when the removablerim is in place we .may employ a positive locking devlcef-or this pur ose. A very. simple and eflicient form 0 such a locking device consists ,as shown, of a slidable slotted plate I one end of which is formed with a recess that conforms to and is adapted to engaginglyspan the wrench seat 2 of the ec' 5 centric member D. The plate or slide is secured to the i'nnerface ofthe' felly B by means of a bolt which passes throu h the slot 7 formed therein and which is. provi 'ed'with a wing nut for securing the said slide in osition. By loosening the wing nut, the slide I ma be moved into or out'ofengagement wit the eccentric member D.

While we have illustratedin the drawings aeleneher tire H having an outer c'asingl and an inner tube 2 -it is to be understood that with a longitudinally extending cylindricalthe particular form of tire is not a material tuate the yokes F to cause the abutting ends of the removable rim E to separate, thus increasin the diameter of said rim after which the said eccentric member D and the attached valve G are inserted through the hole in the felly, and the rim E carryin the tire is swung into the plane of the inter ocking band C and felly B. The eccentric member D is then turned a-half revolution, which causes the co-acting yokes F to draw the ends of the removable rim E together, thus decreasing the diameter of said rim and causing the channel 1 thereof to closely engage the corresponding bead or rib 1 formed on the member C. is employed, is then secured in locking engagement with the eccentric member D, and the wheel is readyfor use.

When it is desired to remove the tire H and removable rim'E, the eccentricD, after having been freed from the locking slide I, is rotated a half turn to cause the expansion of the removable rim through the agency of the The locking device I, when such cams 1 l and yokes F, F, aspreviously explained. This expansion of the rim E enables it to be tilted or swung about its point of connection with the eccentric member D sufficiently to clear its opposite side from engagement with the circumferential bead 1 upon. the member 0, in which position it may be entirely detached by moving it over the face of the wheel so that the eccentric member D is withdrawn from its aperture in the folly-B. The attachment and removal of the removable rim shown in Figs. 7 and 8 is accomplished in a similar manner.

Having thus described our invention, what we claim and desire to secure by Letters Patout is:

'1. In a vehicle wheel, the combination with the felly, of an expansible split rim having tire engaging flanges, an eccentric member havin oppositely disposed cams and an enlarged ea rim extending ,beneath said enlarged head, and means operatively connecting said eccentric member withthe ends of said rim.

I 2. In a vehicle wheel, the combination with the felly, of an expansible' split rim having tire engaging flanges and ends recessed to receive an eccentric member, an eccentric the ends of said expansible said cams and extends over the recessed'ends of said rim, and yokes pivotally connected to the ends of said rim and engaging said devices, of an expansible rim which is provided with tire engaging flanges and with a circumferential lockinggroove on its innerface, said locking devices being fixed with respect to said felly and engaging "said locking groove, a plurality of yokes mounted upon said rim, and an eccentric member for actuating said rim through said yokes.

4. In a vehicle wheel, the combination with the felly, of an expansible split rim having tire engaging flanges, said telly and rim having interfitting lockin'g devices yokes pivotally mounted on said rim, and a tubular eccentric member adapted to receive a valve stem, said eccentric member co-acting with said yokes to cause the engagement and disengagement of the interfitting locking devices 'ofthe felly and rim.

5'. In a vehicle Wheel, the combination with the folly, of an -expansible split rim having tire engaging flanges and provided on its inner face with a circumferentlally extending recess,- a lurality of bolts carried by said felly, the eads of said bolts extending into the said circumferentially extending recess of the rim, yokes connected to the ends of the said expansible rim, and a rotatable eccentric having separate cams for actuating each of said yokes.
